E-texts can have embedded audio, video, and other multimedia content. To meet accessibility standards, each type of content needs to be presented in multiple modes (for example, auditory material must be augmented by a viewable transcription). Introducing multimodal information, such as captioning for videos, requires permission from the owner under applicable copyright laws.
- All audio only content must be accompanied by a text transcript.
- Videos and multimedia that contain auditory information must be captioned.
- Copyrights must be observed and complied with as required.
